APPARATUS FOlR REMOVING OLD IPAPER FROM WALLS.

Patented Feb. 20,1912.

Application filed February 25, 1911. Serial No. 610,915.

- To all whom it may concern:

Be it known that we, WAYNE O. ROBERTS and GEORGE E. CoRsER, citizens of the United States of America, and residents of- H01- yoke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Removing Old Paper from Walls, of which the following is a full, clear, and exact description.

We, having patented under date of Nov. 8, 1910, No. 975,284, an apparatus for softening and removing old paper from walls, have found in the exerciseof the invention set forth in said patent thatwhile susceptible of very advantageous use, it still lacked certain provisions for a maximum of efliciency and convenience; andwe have accordingly devised, developed and put into practical operation in conjunction with the apparatus of the form disclosed in our former patent, certain provisions or devices to the end of greatly increasing the practical value of the same. These improvements have been made to the end of enabling one to have a steam supply at the steaming head within a very short time from the lighting of the burner under the boiler; of enabling one to make use of the head in a more advantageous manner than heretofore by reason of certain adjustable features provided therefor; and of simplifying the apparatus by making the valved water filling means for the boiler and the safety valve as one double duty serving appliance.

The invention is described in conjunction withthe accompanying drawings and set forth in the claims.

In the drawings :Figure 1 is a central sectional elevation of the'complete apparatus; Fig. 2 is a perspective view showing the yoke formed .upper end of the operating handle with certain features of novelty combined therewith. Fig. 3 is a cross sectional view on line 33, Fig. 1, Fig. 4 being a partial horizontal sectional view as taken on line 44, Fig. 1; Fig. 5 is a plan view showing the peculiar arrangement of the pluralized heating coils which areem ployed beneath the boiler.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the boiler of cylindrical shape comprising outer shell a, bottom 6, top 0 and inner annular shell cl having a widened lower portion d, and open at its top (i below the top 0. of the boiler proper, and an upwardly opening annular shell f of larger diameter than the inner shell and having at its lower portion 1" a closed relation to the inner shell so that an annular air space 9 is created between the concentric shells (Z and f, which space opens upwardly as shown and has a .hood or baflie plate It supported by bracket arms k thereover. The internally located concentric upwardly opening shells d and f create in addition .to the intermediate air space separated concentric inner and outer water compartments 5 and j, the same having at the bottom of the boiler communication with each other by way of the port k k.

The boiler is inclosd by a sheet'metal casing B which is of a somewhat larger diameter than that of the boiler, such casing being closed at its top and made with a lower portion which depends below the base of the boiler to form a partial inclosure for the burner D. e

The water supplied into the boiler is heated by passing through ,coils beneath the boiler, the water being taken from the outer portions of the boiler at its bottom and redelivered'upwardly through the bottom of the boiler at the central portion thereof; and the arrangement of the pluralized heating coils isshownby the plan view, Fig. 4, in which 4 of the coils are shown, the opposite upturned ends of which are designated by m m m and m. These pipes are of coiled form, have nested arrangements so as to form a substantially circular mat of coils, the outer upturned extremity of each being extended for a short distance upwardly to communicationwith outer portions of the boiler, while their inner upturned extremities which are in proximity toeach other connect into a central portion of the boiler.

Water filled into the boiler through the 100 supply pipe at is prevented by the hood or baffle plate h from entering either the central water compartment 2' or the annular -air space 9, but is deflected to fall on the downwardly inclined partition wall 0 and will pass through the ports 0 into the outer compartment 7', and thence passing through the port is into the widened chamber at the bottom of the inner'compartment it is.car-- ried in a distributed manner through the four coils, subject to the action of the heater D, and issues through the upturned inner extremity of each coil into the'central portion of the inner compartment; and the steam thus generated'has free passage into the partitionedplf to chamber A in the boiler. The interme iate air space g between the outer and inner water compart ments prevents the inflowing cool water from having a-cooling effect on the highly heated water and steam in the central compartment 2'.

The water supplying passage ,n at the top of the boiler is comprised in a coupling member a, and such passage 72. is formed at its upper end with a valve seat opening n".

and a opening funnel surrounds thejframe.

G represents the valve ada ted to the valve seat and having a stem which extends upwardly and is loosely guided through the top of the frame.

Gr re resents a spring in compression between t e frame and the valve for normally holding the valve closed and making of the device a safety valve, as well also as one to be opened to permit the free pouring of water into, and for supplyin the boiler.

'g'f represents a cam ende lever pivoted on the portion of the valve stem which protrudes upwardly above the frame so that by swinging this cam lever into an upright position, and temporarily leaving 1t in such position, water as required may be readlly supplied into the boiler; and, of course under running conditions the cam lever is swung to its normal horizontal position as represented in Fig. 1.

same form and character as described in our former patent, is carried in manner as explained in said patent at the upper end of the pole or operating handle J but in the mounting of the head at the upper end of the operating handle or pole, provision is made whereby the head is adjustable, revolubly about a horizontal axis, so that its forward working edge may conform to a vertical wall, so that such working edge may conform to a horizontal surface, as that of a ceiling or so that such edge may have any oblique disposition as occasion in some cases may require; such provisions comprising means for the reliable confinement of the head in any of its stated adjustments. And, moreover, the headis also adjustable revolubly about an axis at right angles to noiaaaa The operating handle J has a fork'oryoke l ing opposite trunnions g g in horizontal almement, the ends of the trunnions fitting betlrxween the opposite arms J J of the yo e.

J represents a shaft which extends trans- 'versely through the extremities of the oke arm and loosely through the coupling in the axial line of the trunnions, such shaft havin a heiid J at one end which forms a shoul er in engagement with oneyoke arm, E represents a frame or aperturedshell arran ed in an embracing relation about hove said valve seat, and an upwardly while its opposite extremity, which is formed screw threaded, projects outwardly beyond the other yoke arm and receives'a clamping nut J 6 in screw engagement thereon, as shown in Fig. /3.

J J 7 represent washers of compressible or frictionmg material interposed between the trunnion ends and the inner faces ofthe .sage n is formed.

lhe steaming head shown as having rear and front.walls for the creation of an air space in the back thereof is mounted on a tubular extension t which is passed from front to rear through the double walls of the head, and with a tight engagement into the forward portion of the yoke carried coupling L. This tubular extension has a shoulder a at its forward end which engages the wall of the steaming head and at its portion adjacent and to the rear of the back wall of the steaming head, it is externally screw threaded and receives the engagement thereon of a nut 4) provided for convenience with a lever handle '0 so that by turning the handle of 'the nut in one direction, the head will be held firm and rigid relatively to the yoke carried coupling member, while, upon the loosening of the lever nut the head may be revolubly adjusted around the axis of the tubular extension of the coupling L, which extension has its length extending right angularly to the shaft J and trunnions g g.

It is manifest that the partsin combination and arrangement as described, and having constructions as shown and described, produce a wall paper remover, of great practical value to paper hangers, susceptible of production at comparatively small cost.
